"Aviaflight mode": Wifi blocked

Question

I'm using Ubuntu 12.04 LTS on Lenovo B560. Core Linux 3.2.0-34-generic-pae

I have set Wifi switcher "on" and Driver Broadcom STA "on".

Window "Network" --> "Aviaflight mode" isn't switched off. I added "blacklist acer_wmi" in /etc/modprobe.d/blacklist.conf.

WiFi doesn't work. (rfkill list: Hard blocked: yes).

How to switch off "Aviaflight mode" in Terminal?

What is the position of switch #1 here? Does Fn+F5 change anything? What is the entirety of:

rfkill list all

rfkill list: 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no 1: phy0: Wireless LAN Soft blocked: no Hard blocked: yes switch #1 - "on". Fn+F5 - no reaction. The problem appeared after updating (only official 12.04). Problem options: new kernel 3.2.0-34 (?) or the mode of air flights (is always included and blocks wireless).

Does the problem disappear if you interrupt the boot process at the GRUB prompt and boot into an earlier kernel? Was acer-wmi loaded when you first installed? Did blacklisting it help in earlier kernels? I believe 'flight mode' is immovable if the wireless radio is hard-blocked by the hardware switch or at least if the operating system thinks it is.
